Gemini Pro has compiled a list of well-reviewed solid-state portable power bank brands available in Taiwan, along with [CHATGPT Recommendations】, The top three rankings are the same, with the Enerpad UFO series being the top choice in both cases; however, the order of second and third place—Gemini and ChatGPT—is reversed.
What are the differences between solid-state, quasi-solid-state, and semi-solid-state batteries?
【Solid-state battery】is a term for rechargeable batteries that emerged on the market in the second half of this year. Unlike the 【All-Solid-State Battery (ASSB)】—which will soon be used in electric vehicles and has 0% liquid electrolyte by weight—there remains debate over whether explosion-proof batteries that still contain a small amount of liquid electrolyte should be called solid-state, quasi-solid-state, or semi-solid-state battery remains a subject of considerable debate. Even Gemini believes that power banks on the market claiming to use solid-state or quasi-solid-state batteries are merely playing word games—and that labeling them as “semi-solid-state” batteries is the only honest marketing approach??
The lower the weight percentage of liquid electrolyte in solid-state batteries, the greater the difficulty and cost of mass production.According to the author’s definition, a battery with wt% < 5% can be classified as a 【Solid-State Battery (SSB) or Quasi-Solid-State Battery】, while one with wt% ≥ 5% is classified as a 【Semi-Solid-State Battery】. It is understood that in mainland China alone, there are currently at least three manufacturers claiming to produce [solid-state/quasi-solid-state/semi-solid-state] battery cores, with slight variations in the weight percentage (wt%) of the SSB battery cores they provide. With all-solid-state batteries set to enter mass production as early as the first quarter of 2026, it is expected that more manufacturers unable to mass-produce all-solid-state batteries may enter the 【solid-state/quasi-solid-state/ semi-solid-state batteries】, and it remains unclear which SSB cell suppliers individual power bank manufacturers will adopt; in fact, some products sold on cross-border e-commerce platformsExtremely low price, no certificationProducts marketed as using solid-state batteries are suspected of using traditional lithium-polymer battery cells instead. Although most genuine solid-state battery cells are expected to offer varying degrees of puncture and explosion resistance, the percentage of solid-state material (WT%) directly affects the cell’s lifespan and stability. Ultimately, it all boils down to the adage: “You get what you pay for.”。
Since only a few manufacturers currently specify the weight percentage (wt%) of the liquid electrolyte in their SSB batteries, when power bank manufacturers claim their products are “solid-state,” “quasi-solid-state,” or “semi-solid-state,” it’s best to “pause, observe, and listen” before making a purchase.
